LOOM-SI-IUTTLE.

Specification of Letters Patent.

Patented July 8, 1919.

Application filed July 2, 1917. Serial No. 178,108.

To all whom it may concern:

Be it known that I, JEAN B. DA'UDELIN, a citizen of the United States, residing at Fall River, county of Bristol, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Loom- Shuttles, of which the following is a specification.

This invention relates to hand threading loom shuttles, and has for its object toimprove and simplify the construction of such shuttles. Shuttles of this class are usually provided with a threading slot extending longitudinally along the top face of the shuttle, from the inner or intake end of the shuttle eye and'at the side of the shuttle connecting with a second slot which extends horizontally along the shuttle side and enters the shuttle eye near the outer or delivery end thereof. In threading, the filling is drawn through said connecting slots and laid in the eye, after which it runs directly through said eye from the bobbin.

According to the present invention, the horizontal threadingw slot leads into a suitably guarded passage'formed in the shuttle body above the shuttle eye and connecting with said eye from a point above. In

threading, the guard device deflects the filling into said passage from whence it drops into the eye, and in the run of the shuttle, said device acting to prevent improper escape of the filling from the eye. The filling is protected from chafing against the wood of the shuttle by a series of three posts or pins, one of which is located at the inner end of the eye substantially in the line of the bobbin or other weft-carrier and acts as a snubloing post for the'fillii'ig as it is drawn from the bobbin through the eye, and the other two posts being located at opposite sides of the delivery end of the eye and acting as guides to prevent chafing at these points. Preferably, all posts are made of some smooth, hard ungroovable material, such as glass, porcelain or other vitreous substance, and although frangible, are so mounted as to be protected against breakage. As will be evident, my invention dispenses with the usual metallic, porcelain,

Wire or other threading device usually lo cated in the threading eye.

The construction and operation of my invention is fully disclosed in the specification which follows, and particularly pointed out in the appended claims. Throughout the specification and drawings, like reference characters are correspondingly employed to indicate similar parts. In the drawings Figure l is a plan view of the threading end of a shuttle in accordance with my invention.

Fig. 2 is a plan section on the line 2-2 of Fig. 8.

Fig. 3 is a side elevation.

Fig. i is a transverse section on the line 4 l of Fig. 3, and

Fig. 5 is a detail view of the guard for the eye, removed, and illustrating in dotted lines the applied position thereof.

I have indicated at 1 the shuttle body, at 2 the bobbin chamber, at 3 the shuttle throat, at 4 the eye, at 5- the curved threading slot which extends from the shuttle throat longitudinally along the top face of the shuttle to a point in advance of the eye, thence diagonally down the thread eXit side of the shuttle to meet the horizontal threading slot 6' which extends back to the delivery end of the eye, thus connecting the bobbin chamber and eye for the threading operation. The shuttle is cut away or recessed, as indicated at R, at the delivery end of the eye 4;.

The eye I is counterbored as indicated at 16. This counter-bore is located above the horizontal aXis of the eye and preferably to one side thereof. The slot 6 terminates at the eounterbore. This construction leaves an intervening tongue 7 separating the slot 6 and the eye I. In threading, the filling F from'the slot 6 travels along the tongue 7 into the counterbore 16 from whence it drops down into the eye.

After threading, the filling runs directly from the bobbin B past a snubbing post 13 which is set in a vertical'bore formed in the shuttle body at the juncture of the eye t with the throat 3 and passes out through the eye under the tongue 7 which thereby acts as an overhanging guard to prevent the thread from running back into the slot 6. The snubbing post 13 is disposed substantially in the line of the bobbin and preferably to one side of the horizontal axis of the eye, so that the filling may run therefrom in a direct line under the tongue 7 after the shuttle has been threaded.

In addition to guarding the eye against improper escape of the thread when the shuttle is threaded, the tongue 7 affords a bearing or socket for the upper end of a guide post 12 which is driven through a vertical bore formed from the under face of the shuttle and intersecting the eye at the delivery end thereof. The post 13 is therefore embedded in the wood of the shuttle so as to be protected thereby.

The opposite side of the eye at the delivery end thereof is similarly provided with a guide post 11 which extends through the counterbore l6 and is embedded in the wooden shuttle above the eye. The posts 11, 12 and 13 prevent chafing of the filling against the wood of the shuttle. Preferably all three posts are made of some smooth, hard practically ungroovable substance as glass, porce lain or other vitreous material which, although frangible, are by their peculiar mounting protected against breakage.

The eye 1 is guarded by a suitable guard device 9 which as here shown consists of a staple-like member adapted to be driven from below through the overhanging portion of the shuttle side so as to position its loop end in proper relation to the eye 4 and to the threading slot 6. According to the present invention, the guard 9 is normally a stright staple and is driven diagonally through the overhanging portion 1 of the shuttle side and afterward bent as indicated in dotted lines, Fig. 5, to cause the closed end thereof to depend vertically. It is thus possible to position the closed end of the guard closer to or farther away from the delivery end of the eye as desired, by simply bending said closed end inwardly or outwardly. lVhen correctly positioned, the closed end of the guard lies wholly within the recess R beyond the posts 11 and 12 and spaced from the adjacent outer edge of the tongue 7 a distance sufficient to permit the passage of the thread in the slot 6 past the adjacent leg 9 of the guard in the threading operation.

The operation in threading is as follows. The thread from the bobbin is drawn through the slots 5 and 6 until the leading portion of the thread contacts the adjacent leg 9 of the guard 9. This leg deflects the leading portion of the thread downwardly while the following portion of the thread continues to travel along the upper face of the tongue 7, the leading portion of the thread following the curvature of the closed end of the guard until it enters the counterbore 16 and drops into the eye 1. The shuttle is now threaded and the thread runs direct from the bobbin B past the snubbing post 13 under the tongue 7 and out through the eye, the posts 11 and 12 preventing chafing of the thread at the delivery end of the eye, the overhanging tongue 7 preventing escape of the thread back into the slot 6 by a direct upward movement, and the far leg 9 of the guard 9 preventing escape of the thread upwardly into the counterbore 16.

It will be noted that the guard 9 and posts 1112 are set within the plane of the shuttle side wholly within the recess R so as to be protected'by the surrounding walls of the said recess, and that the posts 11, 12 and 13 terminate short of the top and bottom faces of the shuttle. By counter-boring the eye at 16, the shuttle maker is enabled to insert his saw in this counter-bore and saw out the slot 6 Cross reference is made to my prior application Ser. No. 16,460, filed March 23, 1915, which has resulted in the grant of Letters Patent No. 1,245,627,

patented December 4, 1917.

Various modifications in the form and construction of my device mayobviously be resorted to if within the limits of the ap pended claims.
